Spur gear module 1 z=28 with hub

Product Description

Spur gear module 1, z=28, with hub

This module 1 spur gear (28 teeth, with hub) is used wherever reliable, maintenance-free power transmission via involute gearing is required. The standard material is C45E steel (UNI EN 10083-1), widely used in the construction of gear transmissions, gear racks and module drives.

Technical data

Frequently asked questions

How can a module gear be secured against sliding along the shaft?

Besides a key or a clamping bush, set screws (locking screws) in the hub, thrust washers or retaining rings are also used - the choice depends on whether the transmission operates under variable axial load.

Can gears with different modules be combined in one gearbox?

Absolutely not. Teeth of different modules differ in size and pitch. Any attempt to mesh them will end in the drive jamming or the teeth breaking off immediately on the first revolution of the shaft.

What should I do if I need a non-standard module that is not currently in the standard range?

If time is short and you need a specific size, we offer professional 3D printing from modern glass-fibre-reinforced materials. It is an outstanding, durable solution for an urgently needed spare part, for prototyping or for gears with lower loads, allowing you to restore continuity of operation very quickly.

How can you recognise a manufacturing defect in a gear when receiving the goods?

It is worth checking the radial runout (the gear should not "wobble" on the shaft), the uniformity of the pitch between teeth and the smoothness of the tooth surface - visible burrs, dents or uneven pitch are a signal to file a complaint.

Where is this product used?

Used in the construction and servicing of gear reducers and gear transmissions for agricultural and construction machinery, and wherever precise and repeatable torque transmission matters.

When placing your order, please check the current stock level of this gear - the lead time depends on it and is clearly stated according to the quantity available in the given warehouse.
